Pattern is from Priscilla Tatting Book #2, Fig. 2 page 3. I found that it was published in 1915, but actually I don't know if this pattern is older than the book. By chance, it's the same year that my father's mum was born, in May.
Googling for "vintage tatting pattern daisy edging", it can be found a page via the wayback machine, where the same pattern is rewritten using a modern notation, this is the link: (and I hope it will work for you!)
I've just noticed that I'm wrongly tatting the first leaf, with 14+5-9 instead of 9+5-14, but it seems working as well!
